Front Jacking Location
When changing the front wheel, assemble the jack driver
to the jack and connect the jack driver to the extension
tubes. Place the jack under the axle as close to the tire as
possible with the drive tubes extending to the front. Con-
nect the extension tubes and lug wrench.

NOTE:
If the bottle jack will not lower by turning the dial (thumb-
wheel) by hand, it may be necessary to use the jack driver in
order to lower the jack.
4. By rotating the lug wrench clockwise, raise the vehicle until the wheel just clears the surface.
5. Remove the lug nuts and pull the wheel off. On single rear-wheel (SRW) trucks, install the spare wheel and lug
nuts with the cone shaped end of the wheel nuts toward
the wheel. On 3500 dual rear-wheel models (DRW)
trucks, if the outer tire is being replaced then leave the
inner wheel on the vehicle. If the inner wheel is being replaced remove the outer wheel and replace the inner
wheel. The wheel nuts are a two-piece assembly with a
flat face. Lightly tighten the lug nuts. To avoid the risk of
forcing the vehicle off the jack, do not fully tighten the lug
nuts until the vehicle has been lowered.
Rear Inner Wheel Proper Placement (Dual Rear Wheel Equipped)
CAUTION!
Before raising the wheel off the ground, make sure that
the jack will not damage surrounding truck parts and
adjust the jack position as required.
WARNING!
Raising the vehicle higher than necessary can make the
vehicle less stable. It could slip off the jack and hurt
someone near it. Raise the vehicle only enough to
remove the tire.6

6. Finish tightening the lug nuts. Push down on the lug wrench while at the end of the handle for increased
leverage. Tighten the lug nuts in a star pattern until each
nut has been tightened twice. For the correct lug nut
torque refer to “Torque Specifications” in “Technical
Specifications”. If in doubt about the correct tightness,
have them checked with a torque wrench by an autho -
rized dealer or service station. 7. Install the wheel center cap and remove the wheel blocks.
Do not install chrome or aluminum wheel center caps on
the spare wheel. This may result in cap damage.
8. Lower the jack to its fully closed position. Stow the replaced tire, jack, and tools as previously described.
NOTE:
The bottle jack will not lower by turning the dial (thumb -
wheel) by hand, it may be necessary to use the jack driver in
order to lower the jack
9. Adjust the tire pressure when possible.
NOTE:
Do not oil wheel studs. For chrome wheels, do not substitute
with chrome plated lug nuts.
